Fuel pump unit cover and method of attaching same

Abstract

A fuel pump unit cover that covers a part of a fuel pump unit exposed to the outside of a fuel tank includes opening holes, and is provided as an elastically deformable member. The opening area of the opening holes is smaller than the sum of the cross-sectional areas of components (fuel pipe and wiring harness) passing through the opening holes.

What is claimed is: 
     
       1. A fuel pump unit cover that covers a part of a fuel pump unit exposed to an outside of a fuel tank, the fuel pump unit cover comprising:
 a first cover that covers a surface of the fuel pump unit and has an opening; and 
 a second cover that is attached to the opening of the first cover and covers at least part of connections connected to components, wherein 
 the first cover has a first side wall extending toward the second cover, 
 the second cover has a second side wall extending toward the first cover, 
 at least one of the first side wall and the second side wall has an opening hole, an edge of the opening hole being provided as an elastically deformable member, 
 an opening area of the opening hole is smaller than a sum of cross-sectional areas of the components passing through the opening hole, 
 the first cover is provided with fitting holes which are a plurality of recesses, 
 the second cover is provided with claws which are protrusions projecting toward the first cover, 
 the claws are formed integrally with the second cover, and 
 the claws each include a locking portion that is elastically deformed to be fit into a corresponding fitting hole, of the fitting holes, and is elastically deformed to expand after passing through the fitting hole. 
 
     
     
       2. The fuel pump unit cover according to  claim 1 , wherein
 the first side wall and the second side wall are located overlapping each other on an inner side and an outer side, and 
 the side wall of an upper one of the first cover and the second cover is located outside the side wall of a lower one. 
 
     
     
       3. The fuel pump unit cover according to  claim 2 , wherein
 the opening hole is provided in the second side wall. 
 
     
     
       4. The fuel pump unit cover according to  claim 2 , wherein
 the first cover has the fitting holes and the second cover has the claws such that the fitting holes and the claws form a fitting structure that allows the first cover and the second cover to be fit with each other, and 
 a part of the second side wall of the second cover close to the fitting structure is bendable.
